Black Screens On Monitors: How To Fix Them?
The possibility of multiple causes for the screen to go black makes it impossible to pinpoint the precise issue, whether a hardware or software problem. The following list includes potential solutions for the screen issue.
Viruses, spyware, and trojan horses are common risks to any computer and are often to blame for unforeseen issues like errant screen shutdowns.
Install a strong security program, then scan your machine to determine whether you’re hosting any. Either Windows Defender Antivirus or a third-party program can be used.
Delete Conflicting Apps
Some external programs conflict with your graphics drivers, occasionally resulting in a black screen. The most common examples are driver updaters, app removers, antivirus programs, and graphics-based programs like Nvidia GeForce Experience and AMD.

To test whether the bug goes away, try disabling each one separately. This is how:
- Navigate to the next location: Go to Start > Settings > System to access apps and features. (To avoid navigation, type “Apps and Features” into the search field.)
- Search the list for the program you wish to remove.
- Choose it and click “Uninstall.”
Adjust The Power Options
If your dark screen turns back on in a split second, it can be because you moved the mouse, tapped a key, or did something else that caused it to wake up.
It may have been turned off simply as a power-saving measure. To disable it, go to the next section.
- The Start menu will first appear when you press the Windows icon in the bottom-left or keyword corner of the screen.
- Open the app and search the Control Panel.
- Choose when to turn off the display by selecting “Power Options” from the left pane.
- You can select a power plan in the new window after clicking this.
- If it’s set to “Power Saver,” uncheck the box next to it and select “Balanced” as the new setting.
- Next, select “Change Plan Settings” by clicking the blue link next to this selection. Be aware that this link works with all the current plans, so pay attention to which one you click.
- “Shut down your computer” and “Put it to sleep” are the two choices you’ll notice on the new page.
- Set “Never” for both of them.
- To access the “Change screensaver” area, enter “screen saver” in the search bar.
- Set “None” in the expandable box next to the “Screen saver” header by clicking on it.
- Press OK to confirm your selection and restart the computer to make the changes effective.
Check Out Your Monitor
Your display may occasionally be too old, underpowered, or inefficient to operate for long periods. When you overstress it, it becomes overwhelming. The solution to this problem is to reduce brightness.
Keep Your Connections Up-To-Date
Pull out the connections and begin inspecting them after turning off the PC. Check the connections for obvious cuts, bends, corrosions, or other damage-related signs. Pinch the cable lengthwise to check for an internal circuit short if there isn’t an obvious problem.
Make sure the plastic jacket is covered and tightly fitting. Then, check the ports at the back of the tower for distortion. You can also try your current connection with a different device or port to see if anything changes, or you can replace your wires with a spare set.

Why Does My Monitor Go Black For A Second?
A monitor may go black for a short period for several reasons. Some of these reasons are listed below.
A lack of airflow for the internal components is the main reason for an overheated monitor, although other factors can contribute. This can be brought on by a dust buildup or another blockage preventing airflow through the monitor.
Therefore, before turning it on again, thoroughly clean the display. It should function normally if you restart your computer after allowing it to cool down for a few hours.
When your monitor briefly goes dark before turning back on, there was probably a problem with the cable or the electricity to the device. The monitor’s power cable and other connectors, such as HDMI and display port cables, might be considered among these cables. Swap out any cables to see if that resolves the issue to test this.
Check your cables and hardware with a different monitor if, for some reason, you’re using a DVI rather than an HDMI connection. Consider replacing the display as well. Perhaps you need to replace an obsolete component.
Collection Of Graphics Drivers
Your video card’s drivers could also be the source of the issue. The best course of action for you to take is to update your device if you suspect there may be a problem. This useful article will show you how to upgrade your graphics drivers quickly and efficiently.
If Windows 10 is what you’re running, you should check your display driver. This may be done by navigating to your device manager and locating it quickly. It’s quite rare, but it’s also possible that your GPU has reached the end of its life and is failing you.
This won’t be the case in a new device, but it is still possible if you use a very outdated laptop or computer linked to the monitor. You might need to replace your graphics card if this is the case.
You should use the power chord specifically built for your monitor rather than a generic one because displays frequently come with special power cords. If you can identify which component of the connection between the computer and the display is the problem, you should be able to fix this issue and get everything back to normal quickly.
Refresh Rate Of The Monitor
Lack of the proper refresh rate is one of the most frequent reasons for monitoring blackouts.While watching high-definition television on some monitors with a 60 Hz refresh rate isn’t a major concern, the same cannot be said when it comes to being productive.
You should activate the highest refresh rate on your computer if you’re using it for work. Screen tearing may appear as soon as your computer boots up if your monitor’s refresh rate is set incorrectly.

Hopefully you were able to identify a quick cure for the problem of your monitor going black. Usually, the problem is with the cords connected to the device, but occasionally, something more serious may be at fault.
Any cables could be the issue in this case, but it could also be an issue with your power supply or the monitor’s power button. If this is the situation, you must have it corrected before using your monitor once more.
Frequently Asked Questions
Why does my computer screen suddenly go black?
It’s conceivable that the required voltages are not adequately delivered since this powers your motherboard. The HDMI or VGA cable that connects your monitor to your computer may be damaged or broken. Usually, touching it will result in a black screen, but it can also happen randomly.
What causes the random signal loss on my monitor?
Sometimes your drivers may be to blame if your display randomly loses signal while you’re playing games. They can be damaged, out of date, or simply acting strangely. Run any available graphics driver upgrades to see if it resolves the problem.
Why does the HDMI signal on my PC constantly fail?
A poor connection between the HDMI cable and the device is the most frequent cause of issues. Plugging and unplugging the cable frequently is typical.
What causes the frequent on and off of my monitor?
From your manufacturer’s website, install the latest graphics card drivers to check if this is the issue. Most monitor problems with display turning on or off, monitor going to sleep, etc., are primarily caused by incompatible or outdated graphic card drivers.
